 * A channel to  manage all cache-related interactions for layout
 * when it is dealing with dynamic pages created through 
 * document.write(). This interface provides methods that will
 * help layout save dynamic pages in cache for future retrievals.

   * Append data to the cache entry; opens the cache entry if necessary.
  void writeToCacheEntry(in AString aData);

   * Close the cache entry; subsequent writes have undefined behavior.

   * Set the wyciwyg channels security info
  void setSecurityInfo(in nsISupports aSecurityInfo);

   * Store and read a charset and charset source on the wyciwyg channel.  These
   * are opaque values to the channel; consumers who set them should know what
   * they mean.

   * The return value is the charset.  Throws if either the charset or the
   * source cannot be retrieved.  This is guaranteed to return a nonzero source
   * and a nonempty charset if it does not throw.
